The documentary “The Queen of Versailles” begins life as a juicy guilty pleasure, allowing us to gawk and cluck at the nouveau-riche ostentation of an elderly time-share mogul and his much-younger trophy wife as they build their dream home: a 90,000-square-foot palace that would be the biggest house in America.

And then the economy collapses. And suddenly, in some ways, David and Jackie Siegel are just like us.

Sure, they’re stuck in their 26,000-square-foot mansion in Orlando, Fla., which they’re bursting out of with their eight kids, various nannies, maids and animals and wall-to-wall tacky furniture and artwork. Jackie, a buxom and Botoxed former model and pageant queen who’s about 30 years younger than her husband, rides in the back of a limo to pick up fries at McDonald’s.
